EMT rain-tight compression fittings

Abstract

A connector assembly includes a nut, a first member, a second member, and a third member. The connector assembly is used for coupling a conduit to an electrical device that includes a body having an end with an outer edge and a threaded exterior surface. The nut includes a first angled end, a second threaded end, and an inner cavity between the first angled end and the second threaded end. The nut is configured to be threadably attached to the threaded exterior surface of the body. The first member includes a first edge, a second edge, and is positioned within the cavity and encloses the conduit when the conduit is connected to the body. The second member includes a first edge, a second edge, and is positioned within the cavity and encloses the conduit when the conduit is connected to the body. The third member includes a first edge, a second edge, and is positioned within the cavity and encloses the conduit when the conduit is connected to the body. When the nut is threadably attached to the body, the first edge of the first member slidably mates with the first angled end of the nut, the second edge of the first member is in contact with the first edge of the second member, the second edge of the second member is in contact with the first edge of the third member, and the second edge of the third member slidably mates with the outer edge of the end of the body.

1. A connector assembly for coupling a conduit to an electrical device comprising a body having an end with an outer edge and a threaded exterior surface, the connector assembly comprising:
 a conductive nut comprising a first angled end, a second threaded end, and an inner cavity defined between the first angled end and the second threaded end, the nut being configured to be threadably attached to the threaded exterior surface of the body;  
 a first conductive member comprising a first edge and a second edge, and being positioned within the cavity and configured to enclose at least a portion of the conduit when the conduit is connected to the body;  
 a second conductive member comprising a first edge and a second edge, and being positioned within the cavity and configured to enclose at least a portion of the conduit when the conduit is connected to the body; and  
 a first resilient member comprising a first edge and a second edge, and being positioned within the cavity and configured to enclose at least a portion of the conduit when the conduit is connected to the body;  
 wherein, when the nut is threadably attached to the body, the first edge of the first conductive member slidably mates with the first angled end of the nut, the second edge of the first conductive member slidably mates with the first edge of the second conductive member, the second edge of the second conductive member is in contact with the first edge of the first resilient member, and the second edge of the first resilient member mates against the outer edge of the end of the body, and  
 wherein, when the nut is threadably attached to the body, a portion of the first conductive member penetrates an outer surface of the conduit.  
 
   
   
     2. The connector assembly of  claim 1  wherein the first conductive member comprises a compression ring, the second conductive member comprises a friction washer, and the first resilient member comprises a sealing ring. 
   
   
     3. The connector assembly of  claim 1  wherein the conductive nut comprises a metal, wherein first conductive member comprises a metal, and wherein the second conductive member comprises a metal. 
   
   
     4. The connector assembly of  claim 1  wherein the conduit is conductive. 
   
   
     5. The connector assembly of  claim 4  wherein when the nut is threadably attached to the body, when the first edge of the first conductive member slidably mates with the first angled end of the nut, and when the second edge of the first conductive member is in contact with the first edge of the second conductive member, then the body, the conduit, and the nut are in electrical contact. 
   
   
     6. The connector assembly of  claim 1  wherein the first resilient member comprises rubber.
